Get 5 XP from every bonus XP event. (req 50)

As some of the "descriptions" are a little vague I have had a little trouble finding what to do on some of these so this will be an elaboration on the other solutions. I will list the bonus XP events with tips for getting them complete.

I've broken this list down into two sections the first section are events that you must have at least 3 or 4 people in the game to obtain. The 2nd part lists the rest that can be done with just 2 players.

I also made a little google document checklist that you are free to download/print and use for yourself (put an "x" in the left column to mark as complete and turn the cell green)Bonus Exp Checklist (Google Doc)

Please use the comments to help me fill in things that may be unclear or just bad.

A few notes about session setup:Unless the action states otherwise the best settings are: (To update the games settings press (RB) if you are the party leader while in the party menu)Mode: AnarchyMap: Quarantine/ Crash Site (as these are smaller)Respawn Time: 0:03Health: 50%Regeneration: 50%Movement: 130%Unlimited Ammo: YesEnemy icons: AlwaysTime Limit: 30:00 (If you are only going for one action then you can adjust this down to 10 minutes or something)

Weapons: (varies depending on what you are going for)Backpacks: (varies depending on what you are going for)

================================================3+ player Matches4 players is ideal------------------------------------------------Assist Unlocked at 150 XP"Damage an enemy a teammate then kills"Special set up notes: Must be in a team game type i.e. Team AnarchyWeapons: AnyBackpacks: AnyTip: Easy, shoot a member of the opposite team and then have your team mate finish the job

Heal Teammate Unlocked at 325 XP"Restore at least Half of a teammates health"Special set up notes: Must be in a team game type i.e. Team AnarchyWeapons: AnyBackpacks: HealTip: stand next to your team mate and have another player shoot him (if friendly fire is on you may be able to shoot him yourself) once he is below 50% health just activate your Heal pack (LB) (Your teammate will also get a Survivor Point)

Pack Hunter Unlocked at 550 XP"Be Near a teammate when they kill an enemy"Special set up notes: Must be in a team game type i.e. Team AnarchyWeapons: AnyBackpacks: AnyTip: Just stand near your team mate when they make a kill. If they kill multiple people in the same shot they will all count.

Rescue Kill Unlocked at 700 XP"Kill an enemy near a teammate that has been knocked down"Special set up notes: Must be in a team game type i.e. Team AnarchyWeapons: Any but easiest with rifles that you can get headshots withBackpacks: ConcussionTip: The trick here is you have to be near a teammate while they are on the ground. best to find a building with a small room. Stand in a corner of the room and have your target stand a safe distance away. (so you don’t get knocked down by their concussion blast) now have your teammate stand next to your target but directly between the two of you. This way they will get knocked towards you. Line up a head shot on your target and have the target activate his concussion backpack. As soon as your teammate lands at your feet shoot and kill the target.

Synchronized Kill Unlocked at 900 XP"Kill an enemy at the same time a nearby teammate does"Special set up notes: This requires at least 4 people (2 on each team), Must be in a team game type i.e. Team AnarchyWeapons: Any but easiest with rifles that you can get headshots withBackpacks: AnyTip: pick out who you are going to shoot and line up headshots on each. you can either count down and fire at the same time or have one person shoot and the other react. The “At the same time” part of this is fairly lenient so don’t worry if you don’t get it at exactly the same time which may be due to lag anyway as you should still be close enough to get it.

Vendetta Unlocked at 1,200 XP"Kill an enemy who recently killed a teammate"Special set up notes: This requires at least 4 people (2 on each team), Must be in a team game type i.e. Team AnarchyWeapons: AnyBackpacks: AnyTip: Get your teams together and work out who will be shooting who and in what order. for this example I will use 4 players.

Team 1: Player A, Player BTeam 2: Player C, Player D

D kills BA then immediately Kills DC then immediately Kills A

Players A and C in this example now have 1 “vendetta” point. Repeat 5 times then reverse the rolls on each team

A kills CD then immediately Kills AB then immediately Kills D

Players D and B in this example now have 1 “vendetta” point. Repeat 5 times

Knockdown Unlocked at 3,650 XP"Knock down multiple enemies simultaneously with the Concussion pack"Special set up notes: NoneWeapons: N/ABackpacks: ConcussionTip: Get next to 2 or more opponents and activate your concussion pack (LB) (Will count as 1 knockdown) (If your targets are standing next to a border on the map you can nab Death by Boundary points as well)

Mega Kill Unlocked at 5,800 XP"Kill multiple enemies within 3 seconds"Special set up notes: NoneWeapons: Preferably some explosivesBackpacks: AnyTip: Easiest if you have 2 or more people stand in a group and send a rocket their way

BBQ Unlocked at 17,500 XP"Hit 3 enemies simultaneously with the Arc Welder"Special set up notes: NoneWeapons: Arc WelderBackpacks: Heal*Tip: You don’t need to kill anyone simply “hit” them all with the bolts. so have 3 targets stand in a cluster. then just tap your (RT) until “BBQ” point is awarded then have the group use their heal packs and hit them again when they are at full health.

Lined Up Unlocked at 33,000 XP"Hit 2 or more enemies with one Rail Driver shot"Special set up notes: If using 3 people make sure the opposition has 2 peopleWeapons: Rail DriverBackpacks: Heal*Tip: You don’t need to kill anyone simply “hit” them all with the shot, preferably not in the head area but must contact both bodies. so have 2 targets stand in a line. Shot them once (RT) “Lined Up” point should be awarded then have the group use their heal packs and hit them again when they are at full health.

2 player Matchesnote: these can be done faster and more efficiently with more people but 2 is the minimum------------------------------------------------Crush Unlocked at 1,500 XP"Kill an enemy with building debris"Special set up notes:Weapons: Pistol, Singularity Bomb, *ReconstructorTip: The best way I've found to do this is to have them stand next to a building wall. place a Sing. bomb at their feet then quickly switch to your pistol and fire 3 shots into their chest before the bomb goes off. That way their health is low because what you need to have happen is a piece of the building that gets caught up in the vortex must hit them and kill them before the explosion happens for it to count as a "crush"

rinse and repeat until everyone has done this 5x note: you may be able to get multiple people in the same blast just make sure to injure them before the vortex starts up*(use the reconstuctor to rebuild walls if you start to run out of debris to use)

Beat Down Unlocked at 1,600 XP"Kill an enemy with a melee attack"Special set up notes: NoneWeapons: AnyBackpacks: AnyTip: Any melee attack will do, doesnt matter if its with a hammer or gun just go to your target and hit (LT)

Survivor Unlocked at 2,600 XP"Recover to full health after nearly dying"Special set up notes: not necessary but you could set regeneration to 100%+Weapons: AnyBackpacks: AnyTip: Have your partner shoot you in the leg until your health bar is flashing (about 3 shots with the pistol in the chest with health set to 50%) wait until your health has fully recovered and you should see a “Survivor” point added you your score. let your partner know that he can shoot you again.

This challenge is best done when you have all of the bonus xp events unlocked, but it is easy to do with 2 people after you reach 11500xp (maybe 9500xp, but I can never get "Crush" or "Charge" to work). Set up this game in Custom Match:

Just putting this together to show one of, if not the fastest way to get you to 15 Bonus objectives in 1 life.

-- If you did everything correctly and you have all Exp events unlocked P1’s hidden challenge should pop up here--
